DUM'PING-WAGON.

SPECIFICATION forming part of Letters Patent No, 332,818, dated December22, 1885.

Application filed September 19. 1885. Serial No. 177,623. (No model.)

To all whom it may concern.-

Be it known that I, FRANK C. MILLIKEN, of the city and county of SanFrancisco,and State of California, have invented an Improvement inDumping-Wagons; and I hereby declare the following to be a full, clear,and exact description thereof.

My invention relates to that class of dumping-wagons in which the bottomof the bed is hinged to the side sills and is divided on a centrallongitudinal line, whereby it is adapted to swing downward, thusproviding an opening through which the load is discharged.

My invention consists of a novel means by which the parts of the bottomare returned to position; means by which they are firmly held 5 means bywhich they are released to discharge the load; the construction of therunning-gear of the wagon; a novel connection between the front of thewagon-frame and the pole; in a novel brake mechanism, and other detailsof construction, all of which I shall hereinafter fully describe.

The object of my invention is to provide a simple and effectivedumping-wagon.

Referring to the accompanying drawings, Figurelis a plan of mydumping-wagon. Fig. 2 is a transverse section of same. Fig. 3 is a sideelevation.

A are the axles, and B the wheels, of the wagon.

C are the bolsters, and D are the longitudinal parallel sills supportedon said bolsters.

E is the body or bed of the wagon. F is its bottom, which consists oftwo independent parts, meeting on the central longitudinal line of thebed. The outer edges of these boards are hinged to the outer edges ofthe sills by means of the pintles f, journaled in sockets 6. By thushinging the bottom boards to the outer side of the sills the boards whenthey drop down to a vertical are thrown out beyond the vertical plane ofthe inner surface of the bed and entirely out of the way, making anopeningin the bed which is as wide as its bottom. On the front of thewagon-frame, which projects beyond the forward end of the bed as a sortof platform, e, is a vertical spindle, G, provided with a crank-wheel,9. On this spindle is a ratchet-wheel, g, with which a pivoted pawl,engages, whereby the spindle may be held or relieved, when necessary.

Secured to the spindle G is a chain, H,which extends backwardly and isguided downwardly by an angled pulley, h. It thence passes under the bedof the wagon and under pulleys I, which are secured to the bottomboards, F, at or near their meeting edges; thence said chain extends tothe other side of the bed, and is attached to a hook, j, which issecured to the bed. This hook is provided with an adjustable ring, J,which when in place holds the chain on the hook; but when it is desiredto remove the chain, the ring J is slipped up over the point of thehook, thus freeing said point so that the chain can be taken off.

When the driver wishes to discharge his load, he kicks the pawl 9 out ofthe rack 9, thereby relieving the spindle, and the chain under theinfluence of the weight of the load pays out and allows the bottomboards to swing downwardly, whereby the load is discharged. The driverthen turns the spindle G so as to wind up the chain H, which raises thebottom boards again to position where they may be held by the pawl gengaging the ratchet 9; but in order to relieve the chain from theweight of the load I have the following locking mechanism for the bottomof the bed: Under the bed in suitable guides at the front and rear arepieces or strips K,which are adapted to be pushed in far enough to passunder the ends of the bottom boards and to hold them and to be withdrawntherefrom to relieve them. In order to accomplish this movement, I havethe lever L passing upwardly through a slot in the platform 6 and aslotted guide,as shown, and having its lower tending downwardly, withwhich are connected links of, the forward ends of which are attached tothe rear lock-strip, K. When the bottom boards are in position ready toreceive a load, the driver pulls back the lever L, which, through theintermediate devices described, causes the stop-strips 'to move underthe ends of the boards F to lock them in position. When about to dumpthe load, he throws the lever L forward, whereby he withdraws thelock-strips, and he then releases the chain H, as heretofore described.

It will be observed that I have no reach nor hounds 011 my running-gear.This leaves the space between the two axles entirely free and preventsany interference with the discharging of the load; but in order toconnect the forward portion of the running-gear with the frame of thewagon I have the chain 1?, the upper end of which is connected with astrong bail, 19, secured under the forward portion of theplatform 0, itslower end being connected with a bail, p, on the tongue 0. The usualking-bolt is present, though not shown. The rear ends of the sills Dproject backwardly and carry in suitable guides the sliding beam Q, ofthe brake g. This beam, it will be observed, is back oft-he rearwheels,and its blocks The beam Qis operated by means of theusualdevices, consisting of the lever B in front, the crank r, theconnecting'rod 1*, rear crank, r shaft 1, crank r*, and rod r.

.T are iron braces, connecting the sills of the frame with the bolsters.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a dumping-wagon, the bed E, mounted on suitable running gear, andthe bottom boards, F, of said bed, meeting on a central longitudinalline and hinged at their outer edges,whereby they are adapted to dropdown to a vertical plane, in combination with the chain H, secured atits forward end to a winding mechanism, and passing under the bottomboards of the bed and secured to one side of the bed, whereby saidboards may be raised to position, substantially as herein described.

2. In a dumping-wagon, the bed E, mounted on suitable running-gear, andthe centrallymeeting bottom boards, E,hinged at their outer ,edges, andhaving the pulleys I on their under surfaces, in combination with thechain H, secured to the bed on one side and passing under the pulleys Iand upwardly and forwardly around a guide-pulley, h, the spindle G,having crank-wheel g and ratchet g, and the pawl 9', all arranged andadapted to operoperate substantially as herein described.

3. In adumping-wagon, the bed E, mounted on suitable running-gear, andthe bottom boards, F, meeting on a central longitudinal line and hingedat their outer edges, whereby they are adapted to drop down to avertical plane, in combination. with the horizontallysliding lock-stripsK, mounted under the bed, and adapted to be forced in under the ends ofthe bottom boards to hold them and to be withdrawn therefrom to relievethem, substantially as herein described.

4. In a dumping-wagon, thebed E, mounted on suitable running-gear, andthe bottom boards, F, meeting on a central longitudinal line and hingedat their outer edges, for the purpose described, in combination withlockstrips K, mounted in suitable guides under the bed, and themechanism by which said strips are operated, for the purpose described,consisting of the pivoted and guided lever L, the shaft M, andconnecting-links m, the crank m on said shaft, the connecting-rod N, thecrank it at the rear, the shaft it, having cranks a and the links a, allarranged and adapted to operate substantially as herein described.

5. In adumping-wagon, the bed E, mounted on suitable running-gear, andthe bottomboards, I meeting on a central longitudinal line and hinged attheir outer edges, as described, in combination with the chain II,passing under said boards and secured to one side of the bed and to awinding-spindle, G,

in front, whereby said boards are raised to' position, and thehorizontally-sliding lockstrips K, adapted to move under the ends of theboards to hold them and to be withdrawn therefrom to relieve them,substantially as I WVitnesses:
